CPR often takes the role of the psycho social response to some unreasonably impossible situations and sometimes still carried out when the impression is that the situation is hopeless. It is sometimes obvious to the simplest of assessments that CPR would not be successful in resuscitating the individual. Short of decapitation unreasonable expectations are common. Sometimes rigor mortis is not recognized.
Casual, uneducated, arrogant, and judgmental observation by onlookers is all too often a fact of life
When the situation around a person in cardiac arrest is chaotic and riotous a rescuer cannot be faulted for being unrealistic about the possibility of successful resuscitation. Moving a person while CPR is in process is always counterproductive. The only chance for survival when a patient is moved is that the assessment of cardiac arrest is incorrect and CPR is not actually indicated.
